Abstract:
A method and apparatus for transmitting a Precoding Matrix Index (PMI) in a Coordinated Multi-Point (CoMP) communication system are disclosed. The method includes receiving signals in a same frequency band from Base Stations (BSs) included in a CoMP set, which operate in joint processing mode, selecting a first precoding matrix for each of the BSs using the received signals, generating a second precoding matrix by combining the first precoding matrices, and transmitting an index of the second precoding matrix to a serving BS among the BSs.
